BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a tournament refereeing digital display apparatus, and more particularly, to a digital display apparatus applicable to various tournaments either in drill or in formal game to count gained scores for both sides.

2. Description of the Prior Art

Generally, the result of all kinds of tournament, for example, fencing, judo, boxing etc. are judged by the referee. Being influenced by the referee's subjective point of view, the resultant judgement might be incorrect and unfair. Should the referee be in favor of a particular side, the sportsmanship would be spoiled and bringing about the game an unpleasant and argumentative result.

Of course, most of the qualified referees are honest and prudent in performing their task, but some kernel points and dead corners might slip out of watching of an even keen-eyed referee during bitter fighting between two sides resulting in a misjudgement so as to cause the game a meaningless and argumentative one.

On the other hand, it is not always possible to call for a referee to attend competition in a drilling course, actually it is a antipathy to the players.

For rectifying the above mentioned shortcomings in refereeing tournaments, the inventor of the present invention has dedicated great efforts for years to studying and improving these problems and finally come up with a novel tournament refereeing digital display apparatus provided in this invention.

SUMMARY OF THE INVENTION

Accordingly, the main object of the present invention is to provide a tournament refereeing digital display apparatus which can be utilized to automatically show the scores of the game both suitable for drilling course and a formal game.

The tournament refereeing digital display apparatus has at least a transmitting terminal and a receiving terminal. The transmitting terminal is equipped with a pressure sensor, a control circuit, and a transmitting circuit. The receiving terminal is equipped with a wireless receiving circuit, a control circuit, and a display. Both control circuit and transmitting circuit are fixed onto an effective hit zone on both players. When one of the players exactly hits the other on that effective hit zone forcibly with a strength reaching he predetermined value set for the pressure sensor, the sensor delivers a signal to trigger the control circuit which in turn delivers a signal to the wireless transmitting circuit. This signal is then converted into a radio frequency signal by the wireless transmitting circuit and sent to the receiving terminal.

At the moment when the radio frequency signal sent from the transmitting terminal is received, the wireless receiving circuit at the receiving terminal converts this radio frequency signal to a trigger signal which is transmitted to the receiving terminal control circuit. A signal is delivered from there to the display and an effective hit score will be displayed there on.

In this version, a fair game can be expected, it is also effective to avoid the player to attack at random at the foul zone in vain. The transmitting terminal control circuits and the sensor can be set on the different locations on the player's bodies to represent respective effective hit zones, and the initiation value of the sensor is adjusted such that the refereeing digital display apparatus according to the present invention can be applied to various fighting games.

The transmission terminal circuits and the sensor can be fixed to the effective hit zones on the player's body by sewing, binding or other means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1 through FIG. 3, the apparatus of the present invention has at lest a transmitting terminal 1 and a receiving terminal 2. The transmitting terminal 1 is equipped with a pressure sensor 11, a control circuit 12, and a wireless transmitting circuit 13, while the receiving terminal 2 is equipped with a wireless receiving circuit 21, a control circuit 22, and a display 23.

When the specified zone where the transmitting terminal apparatus is hit with a force of predetermined strength, the pressure sensor 11 delivers a trigger signal to the control circuit 12 which in turn sends a signal to the wireless transmitting circuit 13. After receiving the signal sent from the control circuit 12, the wireless transmitting circuit 13 converts this signal into a radio frequency signal and sends it to the receiving terminal 2.

The radio frequency signal is received by the wireless receiving circuit 21 at the receiving terminal 2, this radio frequency signal is converted into a trigger signal and sent to the control circuit 22 which then delivers a signal to display 23, and a score appears on the display 23 representing an effective score corresponding to that particular hit zone. In this way the different scores appear on the display 23 corresponding to respective hit zones.

FIG. 4 is a schematic view showing transmission of signals. As soon as the pressure sensor 11 is impacted at a hit zone, the pressure sensor 11 is distorted and displaced so as to deliver a sinuate wave signal 111 to the control circuit 12 thereby triggering the control circuit 12 to send a square wave signal 121 to the wireless transmitting circuit 13. Then the wireless transmitting circuit 13 in turn sends a radio frequency signal 131 to the receiving terminal 2. The wireless receiving circuit 21 at the receiving terminal after receiving transmitting terminal radio frequency signal 211, will deliver a square wave signal 221 to trigger the control circuit 22. Being triggered, the control circuit 22 displays the score on the display 23 based on the signal sent from the transmitting terminal 1.

FIG. 5 is a graph showing the variation of the pressure sensor output voltages on different sampling points. At first two sampling points, e.g. point 1-91 and point 2-92 are preset on the sinuate wave curve 31. The distance 10 between two lines perpendicular to X axis respectively drawn from two sampling points. 91 and 92 is the abscissas 10 of the pressure sensor 11 on Cartesian co-ordinate; while the distance between two lines parallel to X axis respectively drawn from two sampling points 91 and 92 is the ordinate 101 of the pressure sensor 11 on Cartesian co-ordinate. The X axis represents time, and Y axis represents value of voltage. The sampling point 2 (91) is set on the peak of the sinuate wave 31, the value of voltage between the wave peak and wave valley is a reference value for intensity of voltage 102. The pressure sensor performs sampling and analyzing voltage every time interval so as to detect the strength of impact thereby judging whether the impact is effective.

Alternatively, the pressure sensor 11 is replaceable by a displacement sensor which performs sensing according to amount of displacement by impact, the stronger the impact, the larger the displacement of the sensor, and vice versa. By so, the strength of force is replaceable by the amount of distance so as to judge whether the impact is effective or not.

In an embodiment of the present invention shown in FIG. 6, wherein the refereeing digital display apparatus is applied to the Japanese fencing. The transmitting terminal l's apparatuses is fixed on the forehead 5, the throat 6, the left wrist 71, the right wrist 72, the left belly 81, and the right belly 82. Only in the case the player hits the opponent at one of the aforesaid six portions with the fencing stick, it is acknowleged to be effective with a score appearing on the display 23, should hitting positions be other than the above specified positions, it would be invalid. By so the tournament can be carried out with a good sportsmanship without any complaint or injuries.

The refereeing digital display apparatus is applicable to other tournaments like Korean judo, boxing game etc. by setting the transmitting terminal apparatuses on the specified zones of the player's bodies and adjusting the sensitivity of the pressure sensor according to the regulations of indivisual games including in a formal competition and a drilling course.

In all, the tournament refereeing digital display apparatus according to the present invention has several noteworthy advantages, namely:

-   -   1. Misjudgement can be avoided so as to carry out the game         fairly and precisely.     -   2. Accidental injury due to foul attack by irritated player         arising from unfair or erroneous refreeing can be avoided.     -   3. Teaching the player to attack his/her opponent body exactly         at the effective portion with a predetermined force in the         drilling course serves to improve the player's fighting         techniques.     -   4. The apparatus is applicable to various tournaments other than         fencing by setting the transmitting terminal apparatuses at the         specified zones on the player's bodies and adjusting the         sensivity of the pressure sensor according to the regulations of         individual games.     -   5.
